As Mayr has recently pointed out, acceptance of the concept of evolution JL through natural selection required the rejection of many previously held ideas. Not only were scientific beliefs about the age of the earth, the nature of geological processes and the causes of biological evolution changed, but since the theory of evolution applied directly to man himself, religion, ethics, and the very foundations of a moral society were challenged. It was not the idea of evolution that was so difficult for people to accept; the idea of steady progress toward perfection, perhaps aided by occasional intervention by a Creator, could be reconciled with traditional European beliefs. Since selection was central to the evolutionary process, however, it was no longer possible to believe in the inevitability of progress or the moral nature of the changing universe. The development of modern genetics showed that the evolutionary process was based on chance mutation, selection, and the fate of genes in
populations. The parts of Darwin’s theories that were least acceptable to the average person were confirmed by an over-whelming body of experimental science.
